No, it's not stanced.
The Ford Mustang Shelby GT350 is packaged as a track-ready car that doesn't need any additional performance modifications. It's also a bargain considering how much money it would take to tune a Mustang GT to lap a track as quickly as a GT350. However, this isn't going to stop anyone from trying to improve on perfection. For those adventurous folk, AccuAir has a suspension modification called the e-level control system that can raise and lower a car to alter cornering abilities.
The real question is, does the GT350 even need help in this department? Check out this clip of the system in action and decide for yourself.
